Patent SE-7900795-L (SE)
Inventor: BERGLUND PER ROODE
IPC: G01B21/08
Filed: 1979-01-30
Abstract: A self-stabilizing position sensor for pneumatic measurement. A nozzle, mounted on one end of a tube, blows compressed air directly against a surface to be sensed. The tube has on its other end an outlet member with restricting openings beyond which is a throttle plate, and a member for controlling a known, essentially frictionless position sensor. The midsection of the tube extends through a compressed-air chamber and through the chamber end walls where the tube is born on air cushions. The portion of the tube inside said chamber has inlet holes for compressed air flowing towards and through the nozzle or reversely towards and through said openings. By virtue of a gap, the throttle plate constitutes a non-sealing cover for a second chamber where the openings open. The sum of the pressure acting on the throttle plate, within the tube and on the free outer surface of the nozzle is balanced by the weight of the movable means consisting of nozzle, tube, outlet member, throttle plate and controlling member, and by elastic or magnetic forces acting on the movable member.

Abstract: Phosphated locust bean gum is cold water soluble and does not require heat or high shear to form viscous solutions in water. Blends of phosphated locust bean gum and xanthan gums are also cold water soluble and such blends will form highly viscous gels in water without the application of heat or high shear agitation. Such gels are useful as suspending media for a variety of materials, e.g., seeds used in fluid drilling planting operations.

Abstract: A method of removing heavy metals, particularly cadmium, from wet-process phosphoric acid produced by digesting raw phosphoric material with sulphuric acid, by precipitating out the heavy metals in sulphide form. The residual sulphuric acid is removed first by neutralization with alkali or as a not-readily dissolved sulphate precipitate. Alkali is added to obtain an Me/P ratio within the range of about 0.05-0.3, where Me is the number of catio equivalents in the alkali and P is the number of phosphorous atoms in the phosphoric acid, whereafter the heavy metals are precipitated out by adding a sulphide compound which is soluble in the phosphoric acid, and the sulphide precipitate removed.

Abstract: The invention relates to gas-operated pressure oscillation generators of the diaphragm valve type, particularly pneumatically operated sound emitters used in cleaning inside spaces of furnaces, heat exchangers and similar apparatus, through which gas is flown such as hot flue gases or exhaust gases from chemical processes tending to form a dust deposit on the surfaces in the space. In such cleaning operations gas-carried pressure oscillations of sound or infrasound frequency are used for physically actuating the dust of the deposit. In such applications it is necessary to cool the interior of the pressure oscillation generator and to blow away dust particles in order not to jeopardize or impair the operation of the generator. According to the invention, a scavenging gas at substantially lower pressure than that of the operating gas is supplied to the interior of the pressure oscillation generator through one or more scavenging gas openings (16) in the seat (7) of the diaphragm valve, said openings being arranged adjacent the surface (10) of the seat engaged by the diaphragm (11).

Abstract: A very low concentration (below 0.03 M) trivalent chromium plating bath in which the source of chromium is an equilibrated aqueous solution of a chromium (III) - thiocyanate complex gives a deposit of unexpectedly light color. Such a bath is employed to produce thin overcoatings of light colored chromium for decorative applications. The bath and process is also used to plate the initial layer of a thick (greater than 5 micron) deposit for engineering applications, the major part of which is plated from a higher chromium concentration bath. Such thick deposits from a higher concentration bath are more cohesive and smoother when plated over an initial layer from the low concentration bath.

Abstract: The thermo-electric heat pump consists of at least two identical units arranged such that each transmits a portion of the pumped heat flow with series-parallel switch arrangements for connecting to a DC power source with the units in series or parallel relative to each other. When high pumped power is required or when units start up after a period of non-operation they are connected in parallel and once desired temperature conditions have been reached change-over to steady state conditions with series connection is made either manually or automatically. The units or group of units may be used to cool or heat any thermally insulated room, cupboard, box, or tank where swift cooling is desired at certain times. Two units of the heat pump (15,16) are of identical design. Their cold sides are connected to cooling elements (17) inside the refrigerator whilst the warm side is connected to a heat exchanger element (18) exposed to the outer air.

Abstract: The roll assembly of a calender has at least one roll with a deformable shell which surrounds a rigid carrier and whose end portions surround discrete antifriction bearings. The intermediate portion of the shell surrounds one or more rows of hydrostatic supporting elements which can be acted upon by adjustable fluid-operated motors to change the shape of the intermediate portion in a plane including the axes of the one roll and the neighboring roll as well as at right angles to such plane. Stresses which are applied to the bearings for the end portions of the shell are monitored by several sensors which transmit signals to a control system to regulate the deformation of the shell in such a way that the stresses upon the bearings are minimized or reduced to zero. This enables the intermediate portion of the shell to undergo deformation which is best suited for optimum treatment of the material passing through the nip of the one roll and the neighboring roll.

Abstract: In a method for detecting the concentration of a primary and emulsifiable contaminant, e.g. oil, in water which also contains secondary, tertiary and possibly other non-mechanically emulsifiable contaminants, such as iron oxide and/or atapulgite, the contaminated liquid is prepared to repeated disintegration of the primary contaminant in an emulsifier to form discrete, homogenous and precise primary contaminant particles in order to maximize the light scatter effect. The liquid is then passed through a measuring cell and irradiated with light from a light source, wherewith the type of secondary and tertiary contaminants present, which cause the light to be scattered in a significant fashion, substantially in a rearward direction, are determined by a detecting primarily the quantity of light reflected at different angles and secondarily the quantity of light transmitted. The total quantity of the thus determined types of contaminants is determined primarily by detecting the quantity of light transmitted and secondarily by detecting the quantity of light reflected, thereby also enabling the concentration of the primary contaminant to be calculated.

Abstract: A twin-wire drying section of a paper machine includes upper and lower rows of drying cylinders, an upper drying wire guided by the upper drying cylinders and upper guide rolls situated between the upper drying cylinders, and a lower drying wire guided by the lower drying cylinders and lower guide rolls situated between the lower drying cylinders. A web is pressed by the upper wire in direct drying contact with the surfaces of the upper drying cylinders and is pressed by the lower wire in direct drying contact with the surfaces of the lower drying cylinders and has a free draw of a certain length between a drying cylinder of one row and a drying cylinder of another row. In accordance with the invention, a vacuum zone in arranged on a run of a drying wire between a drying cylinder and the next guide roll which causes the web to be suctioned against the drying wire so that the length of the free run of the web is substantially shortened. The suction is created by directing air jets in directions opposite to the running directions of the drying wire run and the guide roll which eject air from spaces behind them thereby creating the vacuum zone.
